My three dinner guests:
(1)
Marshall Applewhite [light entertainment]: This crackpot demonstrated the worst that comes by mixing insanity with Christianity. It would still be interesting to find out why men have to cut off their nuts in order to be saved.
(2)
Theodore Kaczynski [heavy discussion]: A tragic life, the "Unabomber" represented a brilliant man whose logic could not save him from mental illness and the stupidity of conspiracy theories. He is still in prison.
(3) and the
UNKNOWN guy who invented beer [the saviour]: He gave us the cure for religion and pseudo-religious fantasy. His "work" continues to help men today. That is more than I can say about the world's religions and quasi-religions.
[the last guy, and his cousins experimenting with grapes, was also appreciated by generations of Romans, Vikings, etc.]
